• The increased positions by several institutional investors, particularly the significant new stakes by Two Sigma and Citigroup, further support a bullish stance, though the complete exit by Millennium Management warrants closer examination of underlying factors.
• Monitor subsequent SEC filings for continued insider buying or selling and further institutional accumulation or distribution to confirm the prevailing sentiment and adjust positions accordingly.
